American Energy Partners LP, the company formed by former Cheasapeake Energy Corp. Chief Executive Officer Aubrey McClendon, agreed to buy acreage in the Marcellus, Utica and Permian Basin in three transactions for a total of $4.25 billion.

American Energy – Permian Basin LLC will acquire about 63,000 net acres in the Permian Basin of Texas from Denver-based Enduring Resources LLC for $2.5 billion, the Oklahoma City-based company said in a statement Monday.

In a separate release, American Energy said its Utica affiliate will purchase about 27,000 net acres in Ohio from East Resources Inc. and an unidentified closely held company. A third American Energy affiliate will buy 48,000 net acres in West Virginia from East Resources and an unnamed company.

McClendon formed American Energy last year after being forced from his role as chairman and CEO of the company he co- founded because of shareholder unrest.

Florida’s state social services agency investigated Nikolas Cruz’s home life more than a year before police say he killed 17 people at his former high school, closing the inquiry after determining that his “final level of risk is low,” despite learning that the teenager had behavioral struggles and was planning to buy a gun, according to an investigative report.
